Of the 23, 2 were eliminated for having significantly higher energy than the others, leaving 21 structures in the final ensemble. The ordered region of the structure includes residues 1-57. Pairwise RMSDs for the ordered region were 0.53 A (backbone atoms) and 1.29 A (all heavy atoms). None of the backbone angles in the ordered region of any ensemble member fell outside the most favorable and additionally allowed regions of a Ramachandran plot. simulated annealing 1 closest to the average 6 mM P22 Cro, 50 mM sodium phosphate buffer, 90% H2O, 10% D2O 90% H2O/10% D2O 3.5 mM P22 Cro U-15N, 50 mM sodium phosphate buffer, 90% H2O, 10% D2O 90% H2O/10% D2O 2.75 mM P22 Cro U-15N, 13C, 50 mM sodium phosphate buffer, 90% H2O, 10% D2O 90% H2O/10% D2O 3.5 mM P22 Cro U-15N, 50 mM sodium phosphate buffer, 100% D2O 100% D2O Bruker collection XwinNMR 3.1 F.
